Conditionally display row using JSF Datatable

Question

I have some JSF code that currently works (as shown below), and I need to modify it to conditionally suppress the display of certain rows of the table. I know how to conditional

Answer 1

Rows correspond to data objects in the collection of your table. If you don't want the row, don't put the object in the collection.

Alternatively, you can use the rowClasses parameter for dataTable.

Bean code:

public String getRowClasses() {
    StringBuilder sb = new StringBuilder();
    for (Data data : myData) {
        sb.append(data.hide ? 'hide,' : 'show,');
    }
    return sb.toString();
}

CSS:

tr.hide {display:none;}
